IMPROVEMENT IN BIT-STOCKS.

Specification forming part of Letters Patent No. 118,039, dated August15, 1871.

To all who/m it may concern:

Be it known that I, WILLIAM H. MoGoY, of Ervin g, in the county ofFranklin and State of Massachusetts, have invented a new and usefulImprovement in Bit-Stocks, of which the following is a specification:

My invention, described particularly hereinafter, is designed to make ahandle for a bit-stock that shall be both cheap and lasting.

Figure 1 is a perspective view of my improved bit-stock. Fig. 2 is anenlarged view of the center part of the stock, with the handle B and itsfer-rule b shown in section.

The handle B is formed first from a block of wood by turning it to theproper size, and boring it through the center, so that when placed uponthe rod it will turn freely. After this operation a circular groove iscut in each end about one-half of an inch deep, with a cylindrical saw,leaving about one-eighth of 'an inch of wood between the groove and thecircumference of the bore. Into these grooves so made the fer-rules b bare forced, so that they are held in the mauner shown in Fig. 2 of thedrawing. The ends ofthe handle B are also beveled within the bore, sothat they will it over and turn upon the conical collars O. Before therod A is bent to the required shape the handle is slipped in place onit, and the conical collars C placed and soldered or fastened on therod, so that they will hold the handle in position, and yet allow it toturn freely upon their inner conical surfaces c c and the rod A A. Therod A is then bent to the proper form, and the other parts-the head andsocket-are united to it; but as they forni no part of this invention adescription in detail is unnecessary.

Before this invention, the handles for bit-stocks were, so far as knownto Ine, made with a hoop or metal ferrule or tube forced over each end,but they were liable to become loosened and slip off the handle, and bethe cause of much trouble.

This invent-ion removes these objections in the construction ofbit-stocks, and makes the hoops or ferrules a permanent part of the handle, strengthenin g it, prevei'iting it splitting, and, at the sauletime, retaining all the advantages gained by having a wooden bearing incontact with the working surface c ofthe collars C.

The cost of producing this handle is much less than is incurred by othermethods of making them, and a much better and efficient handle forbit-stocks is the result.

I claim The handle of a bit-stock with metal tubes or hoops forced intogrooves in the ends of the L. J. GUNN, D. l?. ABERCROMBIE.
